Rotary Shaft Seal 12010977 CORTECO 52x72x10 NBR BA

Applications - reliable rotary shaft sealing

The Rotary Shaft Seal CORTECO 12010977 is a high-quality oil seal designed for effective rotary sealing of shafts in industrial and automotive applications. The BA design makes it suitable for engines, gearboxes, pumps, and mechanical drive systems where reliable oil retention and protection against contamination are required.

With precise dimensions of 52x72x10 mm, this shaft sealing ring ensures stable installation in the housing and consistent sealing performance in continuous operation. It is widely used in industrial applications where durability and repeatable quality are critical.

Advantages - high durability and resistance to oils and grease

Manufactured from NBR (nitrile rubber), this rotary oil seal offers proven resistance to oils and grease and stable performance under standard operating temperatures. The metal outer case provides structural rigidity and secure seating in the housing, while the integrated garter spring maintains constant radial pressure on the shaft.

This construction results in high durability, reduced wear, and long service life. The seal operates as a single lip oil seal, delivering efficient sealing with minimal friction, making it a reliable solution for long-term use in machinery and engines.
